If your air conditioner is working non-stop to keep the soaring summer temperatures outside where they belong, your next utility bill might put a dent in your carefree summer vibe. Fortunately, there are some easy ways to keep those cooling costs in check; you can find several tips on the U.S. Department of Energy website, but here’s a quick run-down of cost-saving tips you can implement right away, plus worthwhile professional fixes:

Easy Energy-Saving Tips

1. Seal Air Leaks: Even small gaps around windows, doors, and baseboards allow cool air to escape and hot air to enter. Use weather stripping or caulk to seal these leaks. This simple fix can significantly improve your home's energy efficiency.
2. Use Ceiling Fans Wisely: Ceiling fans don’t cool a room, but they help you feel cooler by circulating air. Set them to rotate counterclockwise in summer to push air downward. Remember to turn them off when leaving a room to avoid wasting energy.
3. Close Blinds and Curtains: Now might be a good time to upgrade your window coverings for something insulated. Whatever type of covering you have, keep them closed during the hottest part of the day to block sunlight and reduce indoor heat gain. Storm windows or glazing can also reduce heat inside your home.
4. Adjust Thermostat Settings: Set your thermostat to 78°F when you’re home and higher when you’re away. If you don’t currently have a programmable or smart thermostat to automate these settings, consider investing in one.
5. Change Air Filters: Don’t make your AC system’s job harder than necessary; dirty filters restrict airflow, forcing your system to work harder. Check and replace filters monthly during peak summer use.

Professional Upgrades That are Good Investments

1. HVAC System Tune-Up: A yearly inspection by a licensed HVAC technician ensures your system is running efficiently. They can clean coils, check refrigerant levels, and fix minor issues before they become costly.
2. Add Insulation: Many older homes lack sufficient attic insulation, which can cause cool air to escape. A professional can evaluate your insulation needs and properly install additional materials for better energy retention.
3. Duct Sealing: Leaky ductwork can waste 30% or more of cooled air. A professional can inspect and seal ducts, improving airflow and reducing energy use.
4. Upgrade to Energy-Efficient Equipment: If your air conditioner is more than 10-15 years old, consider upgrading to an ENERGY STAR®-rated model. Though it's a higher upfront investment, it uses about 20% less energy, meaning the long-term savings on your utility bills can be substantial.

By combining do-it-yourself fixes with occasional professional support, you can improve your home's energy efficiency and stay cool all summer long – without sweating over your next electric bill.
